Pre-lab Questions
1. What is a model organism, and why is Saccharomyces cerevisiae so often used as one? They
are a species that scientists study in the lab to learn more about biological processes.
Sprouting yeast, or Saccharomyces cerevisiae, is an often used model organic organism due to
its ease of care and ability to adapt to many ecological conditions. Moreover, it provides
similarities to human cells in terms of regulating cell division.
2. Research and discuss the properties of mold that make them sometimes beneficial to
humans, and sometimes potentially harmful.
Mold produces allergens and irritants that can lead to various health issues, including
coughing, nasal congestion, and throat irritation. As a result, being around mold can have a
detrimental impact on one's health. However, mold can benefit people in other ways as well.
For instance, we eat some molds, such as mushrooms, which aid in producing antibiotics, such
as penicillin and other valuable compounds.
3. The lab guide discussed “acellular” organisms. What characteristics classify them as acellular?
Would you consider these living organisms?
"The absence of cell walls, cell membranes, and organelles defines acellular" creatures. Examples of
such organisms are viruses and prions, which lack traditional cellular features. It is debatable
whether or not acellular entities qualify as living things because they lack all of the
Lab 5 Eukaryotic Microbes, Parasitology, & Viruses BIO250L
traits that define life on their own. Even if they can have a substantial biological impact outside of a
host, particularly within a host cell, they might not meet the requirements to be classified as
living things.
